Abstract: Mostly in industrial spray applications pneumatic systems are
utilized for operating the automatic spray gun. Linear motor can be one of the
alternatives for triggering the spray gun instead of pneumatic systems due to
its accuracy in valve positioning according to the required flow rate. From
this point of view a tubular linear permanent magnet motor has been designed
using Permeance Analysis Method (PAM) and developed. Three permeance models
have been developed for PAM analysis. Among these three models, only one model
is selected as a PAM model which can be produced the required amount of thrust
for triggering the spray gun. After selecting the PAM thrust model, the size of
the motor has been optimized by analyzing the effect of thrust constant,
electrical and mechanical time constant. Finally based on the optimized data,
the motor has been fabricated and tested that shows the good argument with the analysis result.
Keywords: Linear motor, thrust constant, electrical time constant, mechanical time constant
